Film With No Glue
« on: November 25, 2020, 09:27:26 PM »
How do you guys go about applying film that has no glue on it?

Got some Coverlite by accident but, I like the color so, I want to try and use it on this foam/ balsa sheeted wing. It says to coat the wing and also coat the film with Balsarite. Does it really need all that glue?

My question is, do I have to coat both, will it stick ok if I just coat the wing?


Thanks,

Motorman,
I have no personal experience but this is a copy of a similar question on RCGroup. It seems to cover what you are asking.

        "Coverlite does not have adhesive on it. Technically, it is also not a film, it is polyester tissue which has been sealed. To apply you either apply the adhesive to the airframe or to the tissue. It is still a heat shrink material so once glued to the frame you can use an iron or heat gun to shrink it.

Make sure what you have. Coverlite is made by Coverite. Coverite also makes film coverings.

Balsaloc is a water based adhesive made for that purpose but is not fuel proof. Balsarite is a fuel proof adhesive made for this stuff.

Balsaloc looks and acts like plain Elmers white glue.

PS Coverite (which is the same material as Solarfilm's Litespan) is my favorite covering material for smaller airplanes (less than 60" span)."

            When covering foam combat wings, I have used 3M 77. I lay the wing on the floor and mist the spray over it. I don't soak it. I just insure that it's covered adequately. I don't spray the film even though that's the proper procedure for most contact adhesives. I lay the film over the foam and use a small shop rag to smooth it all out and I then iron it to remove any unwanted wrinkles.  At the overlaps, I use a strip of clear packing tape which is a real pain to install but when done correctly it works quite well. The problem is when you get the tape near certain films it wants to static cling.

          When I've used Coverlite, they offered two versions of the adhesive, a fabric based version and a film based version. The fabric version was discontinued some time ago and I've used the Coverite version for film with no issues whatsoever. It just seems a bit thicker and I've never tried to reduce it. I just brush it out of the can. It has successfully done undercambered wings with no pull back issues.

Contact cement, usually thinned a bit, is what most f2d planes from eastern Europe use. They put a thin bead on only the le and the and tips. When I cover, I also add a bead on each rib and on the center section as it seems to strengthen the frame a bit.

Film is placed on the frame once the beads are dry. Use an iron to attach perimeter. Trim and roll edges, repeat for bottom of wing. Shrink with heat gun.

I'm thinking this stuff is all the hassle of polyspan combined with all the hassle of monokote.

For a water based adhesive I use Mod Poge. It is available at art and craft stores. 2 coats on the wood, light sand between, let dry, then iron on the covering.

Balsarite works fine, but is solvent based and a pain to use indoors. I have lots of it and no longer use it. Come and get it anyone?
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

You can use allmost any contact cement (diluted) as a thermo-activated glue. Maybe it's better to ask recommendations about which is best from US free flight people. I use for Mylar & Icarex UHU contact glue that's meant for soft plastics. L

   For a covering adhesive, I prefer SIG Stix-It. Use it on anything.
   Type at you later,
